efficiency of grinding media balls

Optimization of mill performance by using

dilute pulp, the grinding zones between the media are not saturated, leading to high media wear rate. A variation in total ball angle can be detected and linked to grinding efficiency and charge expansion. This could help the operator to make the right decision and keep the mill running in such a way as to be close to the optimum pulp
